According to Odaily Planet Daily, Ethereum developer Virgil Griffith went to North Korea in 2019 to demonstrate and provide technical advice on the use of cryptocurrency and blockchain technology to evade sanctions, in violation of sanctions law. In 2022, he was sentenced to 63 months in prison, equivalent to about 5 years in prison. U.S. District Judge Kevin Castel ordered this week that Griffith's sentence be reduced by 7 months to 56 months. The judge said that while noting the defendant's violations during his detention at the Bureau of Prisons, the need to protect the public from further crimes by the defendant has been reduced, and noted the great difficulties the defendant experienced during his imprisonment.
